Standard Hohmann Retractor – 42 mm Blade and 15° Bend for Orthopedic Exposure

Standard Hohmann Retractor, SKU PS-000066, is a reusable orthopedic hand retractor manufactured from solid stainless steel for controlled displacement of muscle, capsule, fascia, and other soft tissue from exposed bone surfaces. The instrument measures 9.75 in (24.77 cm) overall and incorporates a 15° bend, 6 in (15.2 cm) tapered handle, 1.5 in (3.6 cm) blade length, 42 mm blade width, and a square distal tip measuring 25 mm long. The tip narrows from 7 mm at its base to 5 mm at the point, allowing the working end to engage a defined bone margin while the broad blade maintains a wider retraction surface. Two 18.5 mm handle holes provide additional gripping or accessory attachment points. This configuration is used during total hip arthroplasty, acetabular exposure, proximal femoral surgery, total knee arthroplasty, open fracture fixation, osteotomy, and other orthopedic procedures requiring direct visualization of bone. Orthopedic trauma, arthroplasty, reconstructive, and joint surgeons use the pattern in hospital operating rooms and specialty musculoskeletal surgical centers.

42 mm Blade, Square Tip and 15° Retraction Geometry

The Standard Hohmann Retractor works through direct manual leverage rather than a ratchet, spring, pivot, or self-retaining mechanism. Its 25 mm square distal tip is positioned against or immediately adjacent to a suitable bone margin, creating a controlled contact point from which the 42 mm blade can displace surrounding soft tissue. The tip tapers from 7 mm at its base to 5 mm distally, concentrating placement while the broader proximal blade distributes retraction across a substantially larger surface. A 15° bend changes the relationship between the working end and handle so the surgeon or assistant can maintain tissue displacement without positioning the hand directly over the exposed bone. The 1.5 in blade length provides sufficient depth to engage periarticular or muscular tissue while preserving access for drills, saw guides, reamers, reduction instruments, plates, screws, or implant components. Its solid construction transfers hand-applied force without mechanical articulation. The 6 in tapered handle improves directional control and minimizes unnecessary bulk near the wound. Two large circular apertures within the handle provide additional purchase and can support weight attachment when an operative setup specifically uses weighted retraction.

Hip, Knee and Fracture Fixation Surgical Workflow

During total hip arthroplasty, the Standard Hohmann Retractor can be positioned around exposed acetabular or proximal femoral bone margins after capsular release and femoral head removal have established the operative field. The 42 mm blade holds periarticular tissue away while the surgeon identifies acetabular landmarks, removes residual labral tissue, performs sequential reaming, and introduces trial or definitive components. During proximal femoral exposure, the instrument can maintain clearance around bone while broaching, reduction, or fixation steps proceed. In total knee arthroplasty, a broad Hohmann pattern may be positioned along accessible femoral or tibial margins to displace capsule and soft tissue during bone cuts, trialing, or component placement. During open reduction and internal fixation, the square tip can be seated at an exposed long-bone margin while muscle is retracted for fracture reduction, plate positioning, drilling, and screw insertion. Osteotomy procedures use the same principle when the surgeon requires a clear working surface around a planned bone cut. Placement should remain controlled because deep or blind advancement beyond the visible cortex can endanger adjacent neurovascular structures. Retraction should complement adequate surgical dissection rather than compensate for insufficient exposure with excessive leverage.

PS-000066 9.75-Inch Standard Hohmann Configuration

PS-000066 is supplied as a single 9.75 in (24.77 cm) Standard Hohmann configuration with a 42 mm blade and 15° distal bend. The overall length gives the instrument sufficient reach for large-joint and long-bone surgery while keeping the proximal grip outside the central orthopedic working corridor. Its 42 mm blade width provides a medium-to-broad retraction footprint compared with narrow Hohmann patterns used in restricted approaches and extra-wide configurations intended for greater soft-tissue displacement. The 25 mm square tip forms the principal bone-contacting element and narrows from a 7 mm base to a 5 mm distal point. A 6 in tapered handle provides leverage while reducing obstruction around other operative instrumentation. Two 18.5 mm apertures are incorporated into the proximal handle and can function as finger or accessory attachment points depending on the surgical setup. This model is selected when the operative field requires more tissue coverage than a narrow 10–25 mm Hohmann but does not require an extra-wide 70 mm blade. Selection should account for bone size, approach depth, surrounding soft-tissue bulk, available insertion space, and the instruments that must pass adjacent to the retractor during the procedure.

Solid Stainless Steel, Reprocessing and Procurement Documentation

Solid stainless steel construction provides the rigidity and dimensional stability required for a reusable orthopedic retractor exposed to repeated manual leverage against bone margins. The fixed one-piece geometry eliminates moving joints that could accumulate mechanical play, but all surfaces still require thorough decontamination after clinical use. Reprocessing should begin promptly so blood, marrow, and tissue residue do not dry along the square tip, blade transition, tapered handle, or within the two circular apertures. Cleaning should be followed by complete rinsing and drying before visual and functional inspection. Sterile-processing personnel should assess the working end for bending, edge damage, corrosion, surface defects, or permanent deformation of the specified 15° geometry. The blade should remain aligned with the shaft and the handle openings should remain free of retained debris. Terminal sterilization should follow the healthcare facility's validated reusable-instrument process and applicable manufacturer instructions. Peak Surgicals displays CE, FDA, and ISO certification badges on the product listing and provides a 30-day money-back guarantee. ISO 13485 and other regulatory documentation should be retained within institutional supplier-qualification files according to the purchasing organization's applicable requirements.

How does the Standard Hohmann Retractor differ from a Cobra Retractor?
The Standard Hohmann Retractor uses a broad 42 mm blade and tapered square tip that are positioned along a defined bone margin for direct manual retraction. A Cobra Retractor uses a more pronounced curved or hooked distal profile designed to reach around deeper bony contours. The Hohmann therefore provides a relatively broad, flat tissue-displacement surface while maintaining a defined osseous contact point. Cobra patterns are often selected when the surgeon needs deeper circumferential engagement around the proximal femur or acetabular region. Both instruments are manually controlled and depend on appropriate placement rather than a locking mechanism. Selection should reflect operative depth, bone geometry, retraction direction, tissue bulk, and the space needed for adjacent instruments.

Why select a 42 mm Standard Hohmann Retractor?
The 42 mm blade provides a broader contact surface than narrow Hohmann retractors commonly used for small bone margins or confined approaches. This width can displace a larger section of capsule, muscle, or periarticular tissue during hip, proximal femoral, knee, or fracture procedures. The 9.75 in overall length provides reach for large-joint surgery while the 15° bend keeps the handle offset from the working blade. Its 25 mm square tip gives the operator a defined bone-contacting element before the wider section begins retracting tissue. A narrower model may be preferable when access is restricted or only focal retraction is required. A 70 mm Hohmann may be selected when the operative field requires substantially broader soft-tissue displacement and has sufficient insertion space.

What do CE, ISO 13485 and FDA references mean for procurement?
Peak Surgicals displays CE, ISO, and FDA-related certification information for the Standard Hohmann Retractor. ISO 13485 concerns the quality-management system governing controlled medical-device manufacturing and associated quality processes. CE documentation supports conformity review within applicable medical-device markets. United States hospitals and distributors should evaluate FDA-related manufacturer, establishment, listing, and device records according to their purchasing procedures. These references should not automatically be rewritten as a claim that PS-000066 is individually FDA approved unless that precise regulatory status is documented. Procurement teams can retain certificates, SKU identification, supplier records, and purchasing documentation within their institutional vendor-qualification files.

How is retraction controlled when this Hohmann has no locking mechanism?
The Standard Hohmann Retractor is completely hand controlled and contains no ratchet, spring, pivot, or self-retaining lock. The operator first positions the square distal tip at an appropriate visible bone margin and confirms that vulnerable tissue is not trapped beyond the working end. Traction is then applied through the tapered handle, and the rigid shaft transfers this force directly to the 42 mm blade. The 15° bend redirects the line of force while helping keep the handle outside the central operative pathway. Increasing or reducing hand pressure immediately changes the amount of tissue displacement. Continuous manual control allows the assistant to adjust exposure as drilling, reaming, reduction, sawing, or implant placement progresses.

How should hospitals order and reprocess the Standard Hohmann Retractor?
Hospitals should order this configuration using SKU PS-000066 together with the 9.75 in overall length and 42 mm blade specification. Peak Surgicals currently lists the instrument at $60.50 and provides a 30-day money-back guarantee. Standard online ordering can begin with one piece, while institutional purchasing records should retain the exact SKU and dimensional configuration. After surgery, blood, marrow, and tissue residue should be removed promptly from the tip, blade, shaft, handle, and both circular apertures. Cleaning should be followed by thorough rinsing, complete drying, and inspection for corrosion, deformation, altered tip geometry, or unintended changes to the 15° bend. Final sterilization should follow the healthcare facility's validated reusable-instrument cycle before PS-000066 returns to the orthopedic or arthroplasty set.
